Criteria for the WaterWare discrete multi-criteria optimization

However, the default procedure is to use alternatives generated by WRM and the criteria generated there.. A WRM scenario (normal model run or optimization scneario) generates the following default summary criteria (they can be exported for use with DMC with the burron labeled: export criteria). Of course, any sectoral or even node specific riteria (the latter, however, only in sets for one and the same network !) can be added manually as well.
Please note: To make comparison between different structural alternatives and even different river basins possible, all criteria must be normalized to eliminate dominant effects of basin size or other basin characteristics.

Optimization Criteria unit and normalization strategy Overall Supply / Demand ratio maximize Reliability of supply % average over all nodes/days maximize Total shortfall % of total input minimize Unallocated water % of total input meet target Overall water content change % of initial content maximize Total cost, combined Euro per capita minimize Total cost, direct Euro per capita minimize Total benefit, combined Euro per capita maximize Total benefit, direct Euro per capita maximize Net benefit, combined Euro per capita maximize Net benefit, direct Euro per capita maximize Benefit / Cost ratio, combined ratio maximize Benefit / Cost ratio, direct ratio maximize Cost / Benefit ratio, combined ratio minimize Cost / Benefit ratio, direct ratio minimize Economic efficiency, combined Euro per m3 of supply maximize Economic efficiency, direct Euro per m3 of supply maximize Water cost, combined Euro per m3 minimize Water cost, direct Euro per m3 minimize Days of flooding within the water year, max 365 minimize Locations flooded % of control nodes minimize

Basin Characteristics unit Basin size km2 Basin poulation km2 Basin populationdensity /km2 Annual average precipitation mm Annual average temperature degC Runoff coefficient   Please note: Basin characteristics are only used as explanatory variables in the post-optimal analysis ! They can not be selected for optimization.
